Pendulum device includes at least one pendulum mass part, and the pendulum mass part is for example hung in the supporting of rotation by means of bogie wheel or the like
On disk, and it can be performed relative motion along predetermined wobble tracks relative to supporting disk.The structure of the type centrifugal force pendulum device
For example explained with function in the A1 of DE 10 2,006 028 552.Except the centrifugal force pendulum device with supporting disk, it puts matter
The pendulum sub-prime amount of amount part is positioned on the supporting disk both sides, it is also known that a kind of centrifugal force pendulum device, wherein pendulum mass part are pacified
Put between two axially spaced supporting disks.
Damping piece can be in such as slow-speed of revolution or when driving greatly, by centrifugal pendulum during more than operation relative to resting position
Permission angle of throw, contact or contact with each other with supporting disk, can so cause undesirable noise in addition damage.To suppress
The collision, stop part is disposed in pendulum mass part or supporting disk.Pendulum mass part can for example be pacified provided with rubber parts as stop part
The rubber parts is put on the bolt of connection pendulum mass part.
The problem of damping piece has lifetime.Temperature stability, aging and chemical stability make it difficult to protect this
Card.
By a kind of centrifugal force pendulum device known to the A1 of DE 10 2,014 210 489, wherein, stage clip is positioned in pendulum mass part
Between.Stage clip suppresses the collision of pendulum mass part mutually.Because stage clip is under pressure, produces in principle when spring is extruded and cause to bend
Bent risk.In flexing, middle part spring region is offset perpendicular to axle of spring, therefore axle of spring is offset archedly.This

Spring wire is mutually close to, therefore pitch s is equal with spring line footpath d.The number for the spring coil being mutually close to can also reduce or
Increase.For example when stage clip 12 does not stress, two adjacent spring coils 21 can also be snugly into each other.
Since spring end 20, and then spring coil has pitch Smin.Towards spring center 23, pitch is increased to
Value Smax.Spring diameter, that is, outer diameter DA, internal diameter DIAnd central diameter D keeps constant herein.If extrusion spring, then have
The spring coil 21 of minimum pitch, that is, the spring coil 21 being connected with spring end 20, are closed first by the pitch of change
Close, and the spring coil 21 of the region of the heart 23 placement is finally closed in the spring.Therefore spring constant has on spring travel changes
Become, the spring constant namely contacts the spring pressure F and amount of spring compression s factor by F=ks.
Fig. 5 is a kind of alternative embodiment of helical spring 12.The helical spring 12 has as above-described embodiment
It is equipped with the spring end 20 for mutually abutting spring coil.While pitch s is constant on its length L, in two spring ends
Between the middle part spring region 22 that disposes there is the mean diameter of coil D of change.Because used spring wire has on its length
Identical line footpath, therefore it is applicable the relation of above-mentioned external diameter, internal diameter and line width.Based on simplified purpose, the description below only relates to put down
Equal spring diameter D.Spring diameter continuously reduces from spring end 20 to middle part spring region 23 respectively, therefore spring piecewise
The shape of truncated cones in pairs.The difference DELTA D of the mean diameter of coil of two adjacent springs coils 21 is in spring end to middle part spring
It is interregional to keep constant, therefore have in Figure 5, D1-D2=Δ D and D2-D3=Δ D.
In stage clip 12 illustrated in fig. 4 spring center 23 is symmetrical with the pitch s of change.Accordingly, shown by Fig. 5
Stage clip 12 be symmetrical with spring center 23 on central diameter D.
